The beam issue, and its impact on sea keeping abilities is interesting. The destroyer range does not have wide beams but in the 6 m range ocean pro has both 2,34 and 2,60. Would be nice to know how they would perform in a situation total weight would be equal. Out of the blue would guess the narrower would be softer, but who knows? My searider is not the softest hull but still performs well compared to many bigger hard boats in chop, i guess this is at least partly due to its rather narrow hull?

Give me a wide beam any day smooth as silk mine is compared to the narrower ones I've been in.

Humber destroyer 7.0

It isn't just about beam width per se. Otherwise a cathedral hull dory would win hands down & we all know that ain't happening. The hull shape/dead rise/"V" are all factors. A deep v flaring out to a wide beam as in Micks Redbay will offer a forgiving ride, the V cuts the water & softens the entry & the flare gives good deceleration & softens the landing. Into a following sea, a (relative) wide beam presents a blunt point of entry to the wave in front & lessens the tendency to dig in. It's like trying to stab a pickled onion in a jar with the fork handle instead of the sharp end😄

You're unlikely to stuff a Destroyer, even in a following sea, you'd have to be driving very badly to get the bow under water. Back off the throttle a tad going down the wave and apply plenty of power when you reach the trough.They have a high bow and a high lift hull at the bow. I owned a 6.5mtr for a number of years and never got the bow under water. It's also a good boat in a beam sea, particularly if you've got plenty of power - power along the trough and skip over the end of the wave as it subsides then repeat. Good fun and you can keep a good average speed - my favourite way of travelling when I had my Destroyer. If you fit a bow lifting prop, at 7mtrs it'll be a good head sea boat too. 150hp is a little under powered but still satisfactory. Obviously top speed will depend on the weight of equipment the boat has aboard but a lightly loaded 7mtr with 150hp should see about 40knots.

If the boat is in satisfactory condition and the price is right, you're unlikely to regret buying it - imho of course. The deck will be ply sealed below and overlaid with fibreglass. Look for cracks at or near the transom knees, pull the bung in the transom drain well, a good boat will be air tight, you may even hear a hiss or pop as the air moves in or out. If it's full of water, then maybe walk away.

As unlikely as most other deep V Ribs of a similar size but certainly possible, it is in anything in the right/wrong sea!

Good fun though in a way provided you don't take your face out on the console and you can get underway again. LOL

As for a beam on sea, the destroyer with few chines and a high sheer bow will have a fairly wet ride compared to peers with lower now or more chines. It's a bit like the Delta Dash. The wave will rush up the hull and is thrown in a more upwards direction for the wind to blow it in your face. A lower bow (tubes) or chines will force more spray out at a lower angle. Drier ride.

That said, in a chop, head on, or in a following sea, the high sheer bow is great.

Like anything, a positive is a negative in a different circumstance.

More chines give lift and ultimately (negligible) more impact to a smooth hull. So a destroyer head vs an ocean pro (more chines) in a head on sea may give a slightly more comfortable ride. But you'd be sat ever so slightly lower in the water using a little more fuel.

And on it goes....

Ahh! Now we're getting into the black arts😄 most folks think that a prop is a prop is a prop, nope! Props are like car tyres, good, bad, indifferent. By altering the geometry of prop blades, different properties can be bestowed on the prop. A prop can be bow lifting in that it hooks in & pulls the stern down, thus lifting the bow. Other props try & "climb" out of the water, thus lifting the stern (handy on twin engine installations with heavy sterns) this lifts the stern & brings the bow down. This can all be a function of number of blades/rake/cupping/blade shape & size. The Mercury site has a very good section on props & how they work.
